The origin of this wisdom saying is unknown. Perhaps Paul had previously heard it from one of the apostles or their closest associates. Another possibility is that the Holy Spirit gave him inspired revelation. It is even possible that Jesus Christ uttered this saying to Paul during his conversion on the road to Damascus.
It is more blessed to give than to receive. In other words, it is honorable to remain in a state of charity and it is dishonorable to possess a self-centered, disdainful mindset. Neither should we needlessly depend on the efforts of or extort other people.
We should offer food, shelter, and clothing for the homeless. We should comfort the lonely. We should make ourselves available to other people. We should always be prepared to give the greatest, intangible gift that can sooth all longings of the human heart, the gospel. We should always allow the candle of our faith to shine before other people. Thus, the principle of giving has been illustrated and contrasted with selfishness and laziness.
A civilization cannot exist without love, which has its basis in God. Adherence to this principle as quoted from Jesus Christ by the Apostle Paul during his farewell speech at Ephesus is an earmark of Christian piety. Love is the foundation of Christianity. Our love for God and other people should distinguish us from the rest of this world. God is pleased with a cheerful giver (2 Corinthians 9:6-7).
